Production Method 1

In the formula, R¹, R², R³, R⁴, R⁵, R^(a), R^(b), R^(c), A¹, A², A³ and n are as defined above.

Production Method at Step [A]

The indoline carboxylic acid represented by the general formula (2-4) is reacted with a halogenating agent in the presence of an inert solvent to yield a carboxylic acid halide.

Examples of the halogenating agent used in this reaction include phosphorus pentachloride, thionyl chloride, phosphorus oxychloride and oxalyl chloride. The amount of the halogenating agent used is appropriately selected from the range of a 1- to 5-fold molar amount relative to the indoline compound carboxylic acid represented by the general formula (2-4).

The inert solvent used in this reaction may be any solvent that does not markedly inhibit the reaction, and examples include aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as methylene chloride, chloroform and carbon tetrachloride; and halogenated aromatic hydrocarbons such as chlorobenzene and dichlorobenzene. One of these inert solvents may be used alone, and also two or more of them may be used as a mixture. Alternatively, the solvent may not be used.

The reaction temperature in this reaction is usually in the range of about 0° C. to the boiling point of the solvent used. The reaction time varies with the reaction scale, the reaction temperature and the like and is not the same in every case, but is basically selected as appropriate from the range of a few minutes to 48 hours.

After the reaction is completed, the compound of interest is isolated from the post-reaction mixture by the usual method. As needed, recrystallization, distillation, etc. can be employed for the purification of the compound of interest. Alternatively, the post-reaction mixture may be directly subjected to the next step without such isolation.

Production Method at Step [B]

The indoline carboxylic acid amide compound represented by the general formula (2-5) can be produced by reacting the indoline carboxylic acid halide compound produced in the previous step with the amine represented by the general formula (3) in the presence of an inert solvent and a base.

Examples of the base that can be used in this reaction include carbonates such as lithium carbonate, lithium hydrogen carbonate, sodium carbonate, sodium hydrogen carbonate, potassium carbonate, potassium hydrogen carbonate, calcium carbonate and magnesium carbonate; acetates such as lithium acetate, sodium acetate and potassium acetate; and organic bases such as pyridine, picoline, lutidine, triethylamine, tributylamine and diisopropylethylamine.

The inert solvent used in this reaction may be any solvent that does not markedly inhibit the reaction, and examples include aromatic hydrocarbons such as benzene, toluene and xylene; halogenated hydrocarbons such as methylene chloride, chloroform and carbon tetrachloride; halogenated aromatic hydrocarbons such as chlorobenzene and dichlorobenzene; straight-chain or cyclic ethers such as diethyl ether, tetrahydrofuran (THF) and dioxane; nitriles such as acetonitrile and propionitrile; esters such as methyl acetate; and polar solvents such as N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide and 1,3-dimethyl-2-imidazolidinone. One of these inert solvents may be used alone, and also two or more of them may be used as a mixture.

Since this reaction is an equimolar reaction of the compounds, they are basically used in equimolar amounts, but either of them may be used in an excess amount. The reaction temperature in this reaction is usually in the range of about 0° C. to the boiling point of the solvent used. The reaction time varies with the reaction scale, the reaction temperature and the like and is not the same in every case, but is basically selected as appropriate from the range of a few minutes to 48 hours.

After the reaction is completed, the indoline carboxylic acid amide compound represented by the general formula (2-5) is isolated from the post-reaction mixture by the usual method. As needed, recrystallization, column chromatography, etc. can be employed for the purification of the compound of interest. Alternatively, the post-reaction mixture may be directly subjected to the next step without such isolation.

The agricultural and horticultural insecticide comprising the indoline compound represented by the general formula (1) of the present invention or a salt thereof as an active ingredient has a remarkable control effect on the above-described pests which damage lowland crops, field crops, fruit trees, vegetables, other crops, ornamental flowering plants, etc. The desired effect can be obtained when the agricultural and horticultural insecticide is applied to nursery facilities for seedlings, paddy fields, fields, fruit trees, vegetables, other crops, ornamental flowering plants, etc. and their seeds, paddy water, foliage, cultivation media such as soil, or the like around the expected time of pest infestation, i.e., before the infestation or upon the confirmation of the infestation. In particularly preferable embodiments, the application of the agricultural and horticultural insecticide utilizes so-called penetration and translocation. That is, nursery soil, soil in transplanting holes, plant foot, irrigation water, cultivation water in hydroponics, or the like is treated with the agricultural and horticultural insecticide to allow crops, ornamental flowering plants, etc. to absorb the compound of the present invention through the roots via soil or otherwise.

Examples of useful plants to which the agricultural and horticultural insecticide of the present invention can be applied include, but are not particularly limited to, cereals (e.g., rice, barley, wheat, rye, oats, corn, etc.), legumes (e.g., soybeans, azuki beans, broad beans, green peas, kidney beans, peanuts, etc.), fruit trees and fruits (e.g., apples, citrus fruits, pears, grapes, peaches, plums, cherries, walnuts, chestnuts, almonds, bananas, etc.), leaf and fruit vegetables (e.g., cabbages, tomatoes, spinach, broccoli, lettuce, onions, green onions (chives and Welsh onions), green peppers, eggplants, strawberries, pepper crops, okra, Chinese chives, etc.), root vegetables (e.g., carrots, potatoes, sweet potatoes, taros, Japanese radishes, turnips, lotus roots, burdock roots, garlic, Chinese scallions, etc.), crops for processing (e.g., cotton, hemp, beet, hops, sugarcane, sugar beet, olives, rubber, coffee, tobacco, tea, etc.), gourds (e.g., Japanese pumpkins, cucumbers, watermelons, oriental sweet melons, melons, etc.), pasture grass (e.g., orchardgrass, sorghum, timothy, clover, alfalfa, etc.), lawn grass (e.g., Korean lawn grass, bent grass, etc.), spice and aromatic crops and ornamental crops (e.g., lavender, rosemary, thyme, parsley, pepper, ginger, etc.), ornamental flowering plants (e.g., chrysanthemum, rose, carnation, orchid, tulip, lily, etc.), garden trees (e.g., ginkgo trees, cherry trees, Japanese aucuba, etc.) and forest trees (e.g., Abies sachalinensis, Picea jezoensis, pine, yellow cedar, Japanese cedar, hinoki cypress, eucalyptus, etc.).

The above-mentioned “plants” also include plants provided with herbicide tolerance by a classical breeding technique or a gene recombination technique. Examples of such herbicide tolerance include tolerance to HPPD inhibitors, such as isoxaflutole; ALS inhibitors, such as imazethapyr and thifensulfuron-methyl; EPSP synthase inhibitors, such as glyphosate; glutamine synthetase inhibitors, such as glufosinate; acetyl-CoA carboxylase inhibitors, such as sethoxydim; or other herbicides, such as bromoxynil, dicamba and 2,4-D.

Examples of the plants provided with herbicide tolerance by a classical breeding technique include varieties of rapeseed, wheat, sunflower and rice tolerant to the imidazolinone family of ALS-inhibiting herbicides such as imazethapyr, and such plants are sold under the trade name of Clearfield (registered trademark). Also included is a variety of soybean provided with tolerance to the sulfonyl urea family of ALS-inhibiting herbicides such as thifensulfuron-methyl by a classical breeding technique, and this is sold under the trade name of STS soybean. Also included are plants provided with tolerance to acetyl-CoA carboxylase inhibitors such as trione oxime herbicides and aryloxy phenoxy propionic acid herbicides by a classical breeding technique, for example, SR corn and the like.

Plants provided with tolerance to acetyl-CoA carboxylase inhibitors are described in Proc. Natl. Acad. Sci. USA, 87, 7175-7179 (1990), and the like. Further, acetyl-CoA carboxylase mutants resistant to acetyl-CoA carboxylase inhibitors are reported in Weed Science, 53, 728-746 (2005), and the like, and by introducing the gene of such an acetyl-CoA carboxylase mutant into plants by a gene recombination technique, or introducing a resistance-conferring mutation into acetyl-CoA carboxylase of plants, plants tolerant to acetyl-CoA carboxylase inhibitors can be engineered. Alternatively, by introducing a nucleic acid causing base substitution mutation into plant cells (a typical example of this technique is chimeraplasty technique (Gura T. 1999. Repairing the Genome's Spelling Mistakes. Science 285: 316-318.)) to allow site-specific substitution mutation in the amino acids encoded by an acetyl-CoA carboxylase gene, an ALS gene or the like of plants, plants tolerant to acetyl-CoA carboxylase inhibitors, ALS inhibitors or the like can be engineered. The agricultural and horticultural insecticide of the present invention can be applied to these plants as well.

Further, exemplary toxins expressed in genetically modified plants include insecticidal proteins of Bacillus cereus or Bacillus popilliae; Bacillus thuringiensis δ-endotoxins, such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1 and Cry9C, and other insecticidal proteins, such as VIP1, VIP2, VIP3 and VIP3A; nematode insecticidal proteins; toxins produced by animals, such as scorpion toxins, spider toxins, bee toxins and insect-specific neurotoxins; toxins of filamentous fungi; plant lectins; agglutinin; protease inhibitors, such as trypsin inhibitors, serine protease inhibitors, patatin, cystatin and papain inhibitors; ribosome inactivating proteins (RIP), such as ricin, maize RIP, abrin, luffin, saporin and bryodin; steroid metabolizing enzymes, such as 3-hydroxy steroid oxidase, ecdysteroid-UDP-glucosyltransferase and cholesterol oxidase; ecdysone inhibitors; HMG-CoA reductase; ion channel inhibitors, such as sodium channel inhibitors and calcium channel inhibitors; juvenile hormone esterase; diuretic hormone receptors; stilbene synthase; bibenzyl synthase; chitinase; and glucanase.

Also included are hybrid toxins, partially deficient toxins and modified toxins derived from the following: δ-endotoxin proteins such as Cry1Ab, Cry1Ac, Cry1F, Cry1Fa2, Cry2Ab, Cry3A, Cry3Bb1, Cry9C, Cry34Ab and Cry35Ab, and other insecticidal proteins such as VIP1, VIP2, VIP3 and VIP3A. The hybrid toxin can be produced by combining some domains of these proteins differently from the original combination in nature with the use of a recombination technique. As the partially deficient toxin, a Cry1Ab toxin in which a part of the amino acid sequence is deleted is known. In the modified toxin, one or more amino acids of a naturally occurring toxin are substituted.

Examples of the foregoing toxins and genetically modified plants capable of synthesizing these toxins are described in EP-A-0 374 753, WO 93/07278, WO 95/34656, EP-A-0 427 529, EP-A-451 878, WO 03/052073, etc.

Due to the toxins contained in such genetically modified plants, the plants exhibit resistance to pests, in particular, Coleopteran insect pests, Hemipteran insect pests, Dipteran insect pests, Lepidopteran insect pests and nematodes. The above-described technologies and the agricultural and horticultural insecticide of the present invention can be used in combination or used systematically.

In order to control target pests, the agricultural and horticultural insecticide of the present invention, with or without appropriate dilution or suspension in water etc., is applied to plants potentially infested with the target insect pests or nematodes in an amount effective for the control of the insect pests or nematodes. For example, in order to control insect pests and nematodes that may damage crop plants such as fruit trees, cereals and vegetables, foliar application and seed treatment such as dipping, dust coating and calcium peroxide coating can be performed. Further, treatment of soil or the like may also be performed to allow plants to absorb agrochemicals through their roots. Examples of such treatment include whole soil incorporation, planting row treatment, bed soil incorporation, plug seedling treatment, planting hole treatment, plant foot treatment, top-dressing, treatment of nursery boxes for paddy rice, and submerged application. In addition, application to culture media in hydroponics, smoking treatment, trunk injection and the like can also be performed.

Further, the agricultural and horticultural insecticide of the present invention, with or without appropriate dilution or suspension in water etc., can be applied to sites potentially infested with pests in an amount effective for the control of the pests. For example, it can be directly applied to stored grain pests, house pests, sanitary pests, forest pests, etc., and also be used for coating of residential building materials, for smoking treatment, or as a bait formulation.

Exemplary methods of seed treatment include dipping of seeds in a diluted or undiluted fluid of a liquid or solid formulation for the permeation of agrochemicals into the seeds; mixing or dust coating of seeds with a solid or liquid formulation for the adherence of the formulation onto the surfaces of the seeds; coating of seeds with a mixture of an agrochemical and an adhesive carrier such as resins and polymers; and application of a solid or liquid formulation to the vicinity of seeds at the same time as seeding.

The term “seed” in the above-mentioned seed treatment refers to a plant body which is in the early stages of cultivation and used for plant propagation. The examples include, in addition to a so-called seed, a plant body for vegetative propagation, such as a bulb, a tuber, a seed potato, a bulbil, a propagule, a discoid stem and a stem used for cuttage.

The term “soil” or “cultivation medium” in the method of the present invention for using an agricultural and horticultural insecticide refers to a support medium for crop cultivation, in particular a support medium which allows crop plants to spread their roots therein, and the materials are not particularly limited as long as they allow plants to grow. Examples of the support medium include what is called soils, seedling mats and water, and specific examples of the materials include sand, pumice, vermiculite, diatomite, agar, gelatinous substances, high-molecular-weight substances, rock wool, glass wool, wood chip and bark.

Exemplary methods of the application to crop foliage or to stored grain pests, house pests, sanitary pests, forest pests, etc. include application of a liquid formulation, such as an emulsifiable concentrate and a flowable, or a solid formulation, such as a wettable powder and a water-dispersible granule, after appropriate dilution in water; dust application; and smoking.

Exemplary methods of soil application include application of a water-diluted or undiluted liquid formulation to the foot of plants, nursery beds for seedlings, or the like; application of a granule to the foot of plants, nursery beds for seedlings, or the like; application of a dust, a wettable powder, a water-dispersible granule, a granule or the like onto soil and subsequent incorporation of the formulation into the whole soil before seeding or transplanting; and application of a dust, a wettable powder, a water-dispersible granule, a granule or the like to planting holes, planting rows or the like before seeding or planting.

To nursery boxes for paddy rice, for example, a dust, a water-dispersible granule, a granule or the like can be applied, although the suitable formulation may vary depending on the application timing, in other words, depending on the cultivation stage such as seeding time, greening period and planting time. A formulation such as a dust, a water-dispersible granule and a granule may be mixed with nursery soil. For example, such a formulation is incorporated into bed soil, covering soil or the whole soil. Simply, nursery soil and such a formulation may be alternately layered.

In the application to paddy fields, a solid formulation, such as a jumbo, a pack, a granule and a water-dispersible granule, or a liquid formulation, such as a flowable and an emulsifiable concentrate, is applied usually to flooded paddy fields. In a rice planting period, a suitable formulation, as it is or after mixed with a fertilizer, may be applied onto soil or injected into soil. In addition, an emulsifiable concentrate, a flowable or the like may be applied to the source of water supply for paddy fields, such as a water inlet and an irrigation device. In this case, treatment can be accomplished with the supply of water and thus achieved in a labor-saving manner.

In the case of field crops, their seeds, cultivation media in the vicinity of their plants, or the like may be treated in the period of seeding to seedling culture. In the case of plants of which the seeds are directly sown in the field, in addition to direct seed treatment, plant foot treatment during cultivation is preferable. Specifically, the treatment can be performed by, for example, applying a granule onto soil, or drenching soil with a formulation in a water-diluted or undiluted liquid form.
